At the beginning of the feed device is in the condition as shown Ain Fig. 6. By the reciprocating movement of the rod I the thread guide 6 isi correspondingly The catch 22 is adapted for cooperation with a pin 25 which is arranged on-f--u a projection of the carrier arm 5 of the thread Vthe winding .operation v 15 `rriovement of the winding feeler member lg 'is lug 28 exerts on the rearterminal cone I3 of the feeler `carrier sleeve I2', which is maintained in engagement with the screw thread I'I of the y guide spindle only by itsown weight and that of winding feeler cone I0, the feeler` carrier sleeve I2 is raised into such a. positionof inclination `that the screw thread I5 of this sleeve isv moved out of engagement with the screw thread I1, as shown in Figy5. At the same time the feeler carrierrsleeve I2 `bearswith the inner rim I4 disposed at its front end onV the guide spindle I6 from above.

' Due tothe screw thread I5 of the feeler carrier sleeve I2 moving out of yengagement `with the thread Il of the guide spindle Ithe feed ceased and the winding on the spool is finished.

moved, whereby the initial portion of the winding ,21 is formed. by the thread on the 'spool .26.

`After the initial portion of the winding 21`h`as" reached the required diameterthis winding portion contacts with the feeler memberv I in consequence 'whereof vsaid memberl ;is.turned and is yaccordingly advanced Ion the guide spindle I6. In this way the intermittent4 feeding rof the thread guide 6 `begins by the winding feeler member III moving the carrier varm 5 .of the thread guide each time along with it. This is due tothe winding feeler member I0 hitting a ring r5 which is providedon the carrier arm 5 and which, asshown in Fig. `4:, has a vertical cross sectional form similar to a wedge, so that it enters into bearing engagement with thewind- "ingfeeler member I0'only 'by means cfa small sur-face portion. This surface portion's downwardly disposed relative to the guide spindle I6 and-the winding feeler member III," so .that as the winding feeler member. II)` hits the vring' 5';

on the carrier arm ofi the threadfguide 6 thev thread I5 of the feeler carrier sleeve I2 is forced into engagement with the screw thread I1 of the guide spindle, due to the effect of reaction DfES- sure', whereby the'winding feeler member VIII yis"operatively` engaged with the screw thread I'I.A .This feeding operation of the thread guide 6 takes place. provided that the resistance opposed by the compression .spring 1 `acting on the Catch 22 isjf so rockedsas to release the pin 25.-

clampingv sleeve 8 lisA overcome and thus the clamping vmechanism 'constituted by the sleeve 3, the locking balls 9 andthe. clamping sleeve 8 is temporarily released, whereupon thisimecha- .msm-holds the thread'guide 6, after the latter has accomplished its feed step, in the new relative position of this guide to they rod I. i

When the'winding on the spool has almost reached the required length and the winding feeler membery I0 is thusflocated near the end `oi its traverse the slideZO is advanced, that is, displaced in the direction away from theV gear box. from a shaft 35 bymeans of a linkage 36,31, The shaft 35 performs one'revolu- 1on.1.3v i

In the course .of this movement *a projection 20"on the slide 20 meets with the pin 25 on the carrier arm' 5 on the thread guide 6, whereupon the-sleeve I2 carrying the feeler member II'I is pushed upward by meansof an auxiliary'lug meeting withfa lower-portion ofthe terminal cone I3 on the sleeve I2.' The auxiliary lug 28'which Vis mounted onthe carrier arm 5 of .thel thread guide 6 for rocking movementtransversely to the guide spindle I6, against the'vinuencefofspring 2B r(Fig.. 3), eventually cooperates with an annulargroove I3? in the, feeler carrier sleeve I2. Due to the eccentric pressure which the auxiliary.

The feeler carrier sleeve isthen pushed back together with the winding feeler member I0 on the guidespindle I6 into initial position in the angularv disposition which the sleeve hasassumed.r This is effected inthe course of the return -movement of thel slide 2l) by the action of initial yposition thewinding feelermember I0 hits. a stopmember I 6 vonthezguide spindle I6, whereupon in the course; ofthefurther return movement of thejslide 20 the auxiliary lug/28 is pushed o-ut of` engagement with the annular groove I3` of the feelerfcarriersleeve- I2 against springinfluence. .Y Consequently, the feeler carrier sleeve falls back intov` normal `position by the action of its ownrweight.andthe/screw. thread I5 on said sleeve.' enters. into'dengagement with the screw thread I'I. vof the. guide spindle I6. Asthe4 slide! 2D. .in returning approaches the initial position thenose 23 on thepivotal catch 22 meets with a stop armf29, as vshownlin Fig. 4, whereby the The feedV device is then in kcondition for beginning the winding of a fresh cop.

' The modification shown in Fig. `10 differs from the' embodiment .of the invention hereinbeforedescribed solely by the feature thatthe Winding feeler member I0. of this modification is in the form of a disc/being rmly' connected to kthe screw sleevey I2 .by means of a hub portion.

In the modification shown in Fig. 1,1 the thread guide 6 ismounted by means of its associated carrier arm .50u a rod 39 which is partly inserted in ahollow rod 40 which during the operation of the machinev is axially reciprocated fromV a traversing cam member33 by means of adriving member-32-- On vthe hollow rod 40 a compression spring 4I lis pushed which abuts' at one end on a set collar 42 and co-acts at the other end with' a clamping'sleeve 43 which is also pushed on the hollow rod 40. The clamping sleeve 43 cooperates ina similar` manner as kthe clamping sleeve 8 described in connection with -the previous examples with locking balls 44 by means of its conical inner surface around which the balls are distributed. rSaid 4balls are insertedin sockets in the hollow rodM) and can be so Vpressed against the thread guide carrier rod 39 by the clamping. sleeve '.43 that this rod is locked to the hollow rod 40 for` common movement. A stop #recaen to ai certain extent', which adapts" .the

` thev Vguide roller spindle I6 to move transversely of theangular stop mernbe'i` 6 I'to a limited extent. vThe mounting `63 Y-in The secondv 'end portion of the guide spindle' i6 takes its bearing in a horizontal slot of la slot guide 65 which receives'the depending leg of the stop member BI and is: adjustablyar'- ranged in a supporting', member 66 transversely ofthe carrierbar |19. Y A'l'hewinding feeler member 'Hl'trave'ls along 5l Yuntilthe guide spindle I6 hitsfthe depending leg offthe stop member 'Si when the winding reaches itspredetermined max-- imunithickne'ss. Thereupon the windingfeeler` member is intermittently fed parallel to the' axis of the spool tobe woundin accordance with Ythe position of thefguide spindle I6, so l that the cylindrical part of `the winding is producedl in thev required lengtht'e'rmi'nating in a front, end cone. Thevguidevroller I is adapted to yrotate under the bearing-pressure of ytheV windingfeeler member owing yto 'which the thread is? correturriis adjustable relative to a carrier sponding'lyi less lstrained .compared 'with4 the Strainingresulting from the use of ann immovable guide rail for the winding yfeeler member.

VThe `thread guide 6 is arranged on a stirrup 61which is slidingly guided with both of itslegs by a rod `I projectingffrom the machinecasing, one oi thelegs of thestirrup being in' addition slidingly guided on fa rod 68 whereby the stirrup 61 is secured against tilting. VBetween the two Y legsfoffthe stirrup 'lgfwhich provides a driving i member, the clamping mechanism 3, 1,118,95is

arranged on the rod I,'by the action of which the rodfll is elastically coupled tothe thread lguide Ey for conjoint `rmovementjtherewith, due

to the vpresence of a' spring B9 abutting against thestirrup 61. One leg of `the 'stirrup 6l is provided `with a boss 10 which serves'to cooperate withthefeeler disc ID. For the-*purpose 0f initiatingithefeed step `of the guide sleeve 3 theffeeler disc I0 bears against the boss `10 on lthe stirrup 61, so thatfthe clamping or feeding device is temporarily released whilethe resistanceopposed by the Acompression spring `1 acting upon the locking sleeve 3 isover-` of the feed step/ the clampingor feeding kdevice holds thethread guide come. On the completion 6 in its new relative position tothe rod'l which is longitudinally reciprocated from 'the machine casing at a constant throw.

In order to produce the reserve` thread guide 6 is brought into the respective relative position to the spooll to be wound' by automatic means.` f Thereupon the cop winding n proper is produced and then Athe machine 'is restored into the initial condition by`v automatic means.
